Object 490 "Тополь" - "Poplar"

The project of a promising tank developed in the 1980s by E.A. Morozov. Object 490 "Тополь" - "Poplar" mockup The design had some primary characteristics which are worth mentioning. A crew consisting of two people - the gunner commander and the driver. Reducing the crew to two and placing them in a compact, well-protected capsule. The use of a hydropneumatic suspension. In addition to solving the main task - increasing average speeds by improving the smoothness characteristic, it makes it possible to control the tank's clearance, which increases the manoeuvrability and survivability in battle. In addition, the controlled hydropneumatic suspension by changing the trim of the machine allows you to increase the gun pointing angles in the vertical plane. Reducing the crew to two people and placing them in a compact, well-protected capsule with the ...

GTD-1000 - GTD-1000TF - GTD-1250 Gas Turbine Engines

The world's first mass-produced tank gas turbine engine GTD-1000T was created at the Klimov Plant in 1968 for the T-80 main battle tank developed By the special tank design Bureau of the Kirov plant (now JSC "Spetsmash"), which was adopted by the Soviet Army in 1976. Since 1980, a modification of the GTD‑1000TF for T-80B/BV tanks was produced, since 1986 a modification of the GTD-1250 for T-80U tanks. GTD-1250 Engines of the GTD-1250 family as part of the power plants of T-80 tanks are in service with the armies of Russia, Belarus, Cyprus, South Korea, Kazakhstan. Turbine engine GTD-1000T/GTD-1250, which have a large volume-weight capacity and a more favourable traction characteristic compared to diesel engines, provide T-80 tanks with interesting characteristics: - higher operational readiness - easy start-up at low temperatures (up to -40°C) - better cross-country ability on soils with a low load-bearing capacity - best noise and heat-masking qualities - increased ...

Testing tank recoil effects on crew

Any armoured fighting vehicle experiences recoil and shock during movement on rough terrain, firing its main gun or hitting a mine. The most vulnerable of all is the crew which operates the tank. High impulse shock loads can cause a decrease in combat performance or partial crew incapacitation. Such instances carry the risk of head injury. Most dynamic impacts inside an armoured vehicle are transmitted to operators through the seats. While there are protective measures in place, like padded tank helmets and dampening seating (driver only), these may not be enough when MBTs are equipped with more powerful cannons, which exceed the expected recoil absorption provided by the chassis they are mounted on. Historically, test facilities were geared toward validating individual components for resistance to external factors like high-impact pulse loads. Ergonomic testing for crew protection was performed mainly in field tests, near the end of development. While computer-aided systems...

"AGAVA" - "AGAVA-2" and its confusing history

When covering Soviet sight technology there are always some interesting designs and approaches to solving an issue. It is a common fact that the Soviet Union in the 1980s-1990s was quite behind in thermal sight technology. Only in the 1990s, but to be specific in 1992, the Soviet Union now Russia started to field small batches of thermal sights on their tanks, primarily T-80Us and some of the early T-90 variants, which just recently entered service. Russia's journey through creating its own domestic thermal sight traces back to 1982. The 1980s were quite an important time for the 'Krasnogorsk Factory named after S.A Zverev', which is still to date an Optical Engineering and Optoelectronics factory. The factory is primarily known for making domestic Soviet cameras back in the day. However, that's not the only thing that the factory has produced back then. Close to the mid-1980s, the facility was contracted to develop new thermal sight technology for the Soviet Ministry...

T-80 rubber flaps - Part 3

Over half a year ago, I promised to write an article about T-80 rubber flaps and their purpose, which would have completed the trifecta article collection: T-80 aerodynamic features and T-80 MBT engine air filtration and dust prevention systems . This article builds up on the T-80 aerodynamic features topic and will conclude this series. Unfortunately, I have come across zero primary sources, that directly mention the purpose of these rubber flaps, which makes it difficult to write an article with primary sources. There are 2 disputed arguments on this topic; one argument states that the flaps on the T-80s are meant to redirect airflow and reduce air contaminants like sand and dust from entering the engine. The other argument is that these flaps are used as additional protection to prematurely detonate HEAT warheads. I will discuss this topic by only talking about the presence of the flaps on T-80s. Firstly the rubber skirt, is present on the lower frontal plate of T-80s. I...

Soviet Union/Russian thermal sight development history

Related topics: "AGAVA" - "AGAVA-2 "and its confusing history Thermal imagers were classed as; Gen-I, Gen-II and Gen-III. Gen-I sights featured the most basic technology due to them being the first of their type. Gen-II sights commonly improved on Gen-I technology by utilizing similar but more refined technical advancements or used completely new methods. Gen-III sights used new advanced technology that is no longer associated with Gen-II and additionally features new materials for photo-elements and ways of processing. Image 1 (For full resolution open the image in a new tab) The table above represents domestic Soviet and early Russian thermal modules/sights. Generations are split into 3 different time periods, Gen-I sights primarily appeared in the 1980s but also made appearances in the 1990s, Gen-II sights appeared in the 1990s and Gen-III sights appeared in the late 1990s and 2000s. Gen-I systems: Utilize linear photo-receiver with 2 types of indicators; b...

T-90A - a short history of sights

In 2004, the T-90A (Object 188A1) tank joined the Russian armed forces. It included many fire control system upgrades, a new welded turret, and improved mobility. The T-90A Obr. 2004 tank was fitted with a T01-K05 Buran-M Obr. 2004 3rd generation night vision sight, which improved over the previous T01-K01 Buran-PA sight from the T-90 Obr. 1992. --Picture of T-90A with Buran-M Obr. 2004-- In 2005, the tank received an upgrade for the sight, which became T01-K05 Buran-M Obr. 2005, with noticeable differences in the sight's housing. --Picture of T-90A with Buran-M Obr. 2005-- --Picture of T-90A diagram with Buran-M Obr. 2005-- --Picture of two T-90As, one with Obr. 2004 and one with Obr. 2005 Buran-M sights-- Above: T-90A with Buran-M Obr. 2004 sight, and behind it, T-90A with Buran-M Obr. 2005 sight. In 2006, the T-90A had to be brought to more modern standards, so the production of this model with new second-generation thermal imaging sight began. The sight was named ESSA, wh...

BMP-3 ERA topic continuation

This post expands on a previously covered topic, being the BMP-3 with ERA . Potentially sealing this topic until later when more information comes to light.

T-80 MBT engine air filtration and dust prevention systems - Part 2

This article does not specifically cover individual filtration units but is a collection of features across several T-80 engine variants. Since 1976, almost all T-80 variants came standard with gas turbine engines. Early T-80 variants utilized the GTD-1000T, the T-80B and its subsequent variants fielded the GTD-1000TF and the later production models of the T-80U used the GTD-1250. With each iteration, the HP (kW) increased to 1000 HP (745kW), 1100HP (820kW) and 1250HP (919kW). The T-80 uses a monoblock-style engine d eveloped in the 1970s by VNIITransmash "Предприятие п.я. А-7701" , which means the engine block is mounted together with the air filtration system and other vital components. The air filtration unit is made of several parts assembled into a monoblock. The air filtration unit consists of 2 cyclone batteries, 2 oil cooling radiators and 2 cooling ventilators. The 2 batteries contain cyclone filters. There are 14 cyclone filters arranged in a 2x7 pattern on each b...

2E58 tank stabilizer

The majority of the remaining Soviet MBTs in the Russian Army featured different 2-Plane stabilizers. Ranging from the 2E42-2 "Jasmin" on the T-72B to the 2E42-4 "Jasmin" being mounted on later modernization programs of the T-72B, like the T-72BA and T-72B2 "Rogatka-2". Additionally, the 2E42-4 is also mounted on several T-90 variants ranging from the T-90 Obr.1992 being the baseline variant to the more modern T-90A. While the 2E42-4 was more modern than its predecessor, the 2E42-2, it still did not improve the guidance speeds for both horizontal and vertical axes. These speeds still remained the same; 3.0°/sec vertical elevation speed and 16°/sec-24°/sec horizontal guidance speed. ( 2E42-4 documentation ) By the late 2000s, the 2E42-4 was dated and was no longer able to perform that well in comparison with NATO stabilizers, which would outperform it. This forced Russia to start developing a new stabilizer, instead of using the conventional type of previ...
